15 or not 15? What do you think?

Not even. There are four inchers that would give good lows if the horn is large enough, but their small displacement would limit their output. Even horn loaded eight inches is the smallest practical size.

For portable amps. A few inches is enough for permanently installed horns, like they used to use in cinemas.

Said horns were typically loaded with fifteens. For instance the Altec A7, or going back further the Shearer horn.

True. I've recounted this on here previously, but when I played the Hammersmith Odeon (now Apollo) many years ago, they still had the old horn speakers standing unused in the wings. They were massive. I could easily have crawled into the horn throats.

Reassuringly heavy..

The mouths. The throat is the small end where the drivers are mounted. Advances in driver technology allow us to use smaller drivers in horns just as in other cab styles, so where a fifteen might have been required 50 years ago a ten would work as well today. But you're not going to get 130dB at 30Hz from a 4 inch driver, no matter how large the horn.

That is the best bass cabinet ever made, IMHO. Every bass player should have the opportunity to play through one of those.

Reassuringly light, 2 x Eminence 3015LF, endless volume.  No tweetery top end which suits my bass tone.  Best bass cab I own.
